It is very rare for the loft boards to meet naturally on a joist, especially when laying boards over existing joists (which you shouldn’t do). In the best-case scenario the joists will be perfectly parallel to one another and laid at exactly the same centres every time. A floor in a loft that’s been converted must be designed to carry a minimum of 150kg per square m. This is 5 times more than a loft that’s simply been boarded for storage. LOADING LIMIT OF EXISTING CEILING STRUCTURE SHOULD BE CONFIRMED BY A STRUCTURAL ENGINEER. Loft Leg XL’s are sold in boxes of 12 units. How many do I need?

Mark the fixing positions on the board with a pen and drill a countersunk hole through the chipboard only. Loft insulation is an effective way to reduce heat loss and save on your fuel bills. Here we will show you how to fit loft insulation rolls, as well as how to insulate pipes and cold-water tanks Clear as much space as possible to give yourself a large, safe work area. Use any available wooden planks or loft boards to create a flat storage area for a few rolls close to where you’ll be working. Step 4For more information read our project on loft insulation to make sure you have enough insulation in your loft before fixing down floorboards. We’ll show you how to work these out in the sections below. How to calculate the required thermal resistance of loft floor insulation

Pen and paper – to note how much existing loft floor insulation you currently have, joist sizes and spacing, if needed. Adding more insulation when boarding your loft really goes hand in hand and should always be done if you don’t already have the minimum recommended 270mm of insulation. A minimum R-value of 6.1 is recommended for loft floor insulation, but ideally it would be up to 7.0. Both employees and self-employed workers will pay less in National Insurance from next year, Chancellor Jeremy Hunt has announced in today's Autumn Statement.The loft boards should always be installed perpendicular to the joists. Place the first leg into position and using your power drill driver, screw it into the joist. You don’t need to pre-drill holes. Always move slowly and carefully in the loft and work from ‘crawling boards’, moving them along as you go. Never stand between joists and avoid standing directly on joists as much as possible Loft legs are screwed directly into the joists or trusses in a grid to raise the boards. These legs allow you to put down additional insulation across the joists and then install boards on top.

With this in mind always take extreme care when working in a loft. It’s often a good idea to lay some loft boards loose over the top of any joists just so you have something solid to stand on and work from. Step 9 – Fix Upstands in Place: Using 2 x 1 inch roofing batten, cut a piece to length and fix it along the length of one side of the boarding and then repeat this for the remaining 3 sides

Martin Lewis: What the Autumn Statement means for you – including wages, benefits, pensions, ISAs, housing, national insurance and more Step 1 – Prepare Area: Clear the installation area of any objects including already stored items, debris, dust etc. The clearer you can make the area the easier it will be to work Whats happening in this case is that the moisture has been found in effect trying to permeate the boarding, next stop mould followed by rot. Lofts are dangerous places, especially when they’re not boarded as all you have to stand on are the ceiling joists, everything else is non-structural plasterboard that does not support any form of weight at all.
